In Halloween Terror 2017, another enemy was added: the Summoner. An endless horde mode was also included, in which the players have to hold the door for 12 rounds of enemies and bosses rush to win (or continue to hold for 15 more rounds to fight the final boss round).

In Halloween Terror 2018, two new heroes were added : Brigitte and Tracer.

There are 8 Special Achievements tied to this brawl that will unlock sprays when obtained.

The Halloween Terror event introduces temporary reskins of the Hollywood (in Halloween Terror 2016) and Eichenwalde (in Halloween Terror 2017) map. The map reskins replaced the normal map skins in all game mode for the span of the seasonal event. There is also a temporary option for the map reskin in Custom Game.

The Halloween-themed changes in this map include: the time of the match being at night, Halloween decorations and supernatural items that are placed all around the map, giving the map the air of sinister and eerie.

As part of the promotion of the Halloween Terror, Blizzard Entertainment released a set of pumpkin carving stencils. Feel free to download them all from the official site or check out what you want below and print.
